Purpose

This is an "afterburner" to the 1D beam model. By means of Monte Carlo sampling using Moliere's multiple scattering theory, the beam broadening as a function of depth is evaluated and filed as a modified depth dose distribution (pencil beam).
Appropriate dE/dx tables as well as a spectrum data base must be loaded.

Parameters

beamenergy
Calculation for this energy (MeV/u).
targetfile()
Name of file with target material list. If omitted: H2O.
width(w)
Initial FWHM of the beam spot.
projectile()
Projectile to be calculated.
particles(p)
Number of particles to follow initially.
repeat(r)
Number of sample runs.
prefix()
Output file name prefix.
debug
Debug switch. Lots of output !

Examples

 spc * /delete
 spc "$TRIP98/DATA/RF3MM/*.spc" / read
 dedx $TRIP98/DATA/20040607.dedx /read
 scatter / energy(270) 
creates the pencil beam description for 270 MeV/u
